Types of UPVC Door Handles If your upvc door handle needs replacing it's essential to find the best replacement for your home. Locksmiths can supply and install high-security uPVC door handles with extra security features. The most important measurements are measurement A (known as PZ) and the length of the backplate (measurement F). Take these measurements to make sure the new uPVC handle will fit. Lever/Lever A lever is a rigid rod that pivots around an object. When you apply a force at the end of the lever it will tend to rotate the fulcrum in the direction of the force. This rotation multiplies your force and lets you lift or move objects that normally require more force to lift. The distance between the fulcrum of the lever and the point at which you apply force determines the maximum movement. This is called the mechanical advantage. The more the lever is extended more, the greater the mechanical advantage. You can calculate the mechanical advantage by dividing distance from fulcrum point to the place where you apply force by the distance between the fulcrum point and end of lever. Levers can have a variety of effects depending on the way forces are applied. A lever in class 2, for example is prone to rotating in the opposite direction when an force of the effort is applied. If you push the handle of a door, the forces will produce rotational effects similar to this. However, levers don't create energy. Levers increase the force by changing small amounts of effort applied over a long distance into greater amounts of force applied over smaller distances. This is what allows you to do more work in less time, and it is the reason why levers are frequently used to lift heavy objects or moving large quantities of cargo. The lever principle is also used in everyday tools like crowbars. Hammer claws, fishing rods and your own legs, when you are standing on your car's hand brake. Lever/Pad Lever pad handles are a kind of door handle made from UPVC that has levers on both sides to operate the multipoint lock. They are available in a variety of variations & finishes and can be used with a variety of materials including UPVC, Aluminium & Timber doors. They are sold in pairs for the inner and exterior door, with spindles and screws included. They are also available in handed and unhanded versions for different types of users. These can be used to replace an existing doors made of upvc. The levers are raised to open the multipoint locks and the key is turned to lock or close the door. They provide a bit more security than the standard lever handles for doors because locking can only be done by the inside using a key. They are not as safe as a cylinder lock, however they are cost-effective ways to add extra security to your home. The only downside is that they do not offer the same level of protection as a cylinder bolt, and therefore don't stop external access if the door has been left open. The majority of lever pad door handles made of upvc that we stock are made by the industry's leading manufacturers and therefore are made from high quality components. They are also typically supplied with a manufacturer's warranty. Typically, they will be designed to work with a 92mm lock, or the replacement version called a Paddock lock. They will feature an 82mm cylinder centre on the inside, and 62mm outside. They are also fitted with two spindle followers. Some are fitted with the back plate whilst others are movable to enable different fixing centres. Lever/Snib Lever latches are the most basic type of door handles. Pressing down on the lever operates a simple latch mechanism inside the door to keep it closed. It can also be locked using the use of a key. Some lever privacy handles operate similar to the doorknob, but with an additional snib, similar to the doorknob. A snib can be a very useful tool, particularly in homes where security and privacy are essential. You can use the snib button to block your guest from entering until they are prepared. This type of handle is also popular in doors that are inside like bedrooms, where you might require a lock to prevent access from the outside. In certain situations there are instances where snib buttons could cause problems, especially if you have older locks and doors that are warped. If the snib switch is accidentally pressed or by someone who isn't familiar with it, your door may shut and lock you out. In most cases, you can be able to get in by knocking the door's frame or letterbox, however this isn't the best option. If your uPVC has a snib, we recommend replacing it with an electronic lock from the E-LOK 7 Series. These locks can be retrofitted on pull handle kits that double turn and come with cover plates to conceal existing holes for a seamless install. The E-LOK makes use of a smart application that allows you to unlock the door with mechanical keys or RFID cards and can be set up with passcodes to ensure security and convenience. The system has been tested to 200 000 cycles to ensure long-term durability. The handles are constructed of solid metal and comply with BS EN 1670 Grade 5 for resistance to corrosion. Lever/Moveable Pad This is a well-known handle design for front doors that has the advantage of stopping the door from being opened from outside without a key, if the lock isn't deadlocked. This is accomplished by the 'pad'-shaped external handle which locks in the gap between the handles and the lock case to prevent the latch from being withdrawn or the door opened. This handle is designed to work with uPVC multipoint locks which use a split spindle mechanism. This type of operation requires that the internal lever handle and external pad handle be attached to the same lock case. This can be a simple replacement for the current uPVC handle, however it could also require a lock case change or a new set to handle furniture. These aluminum lever/movable pads door handles are suitable to be used on uPVC and come with an unmaintained slide bearing. They also come with fixing lugs spring cassettes and a non-stick slide bearing. These handles have a euro-profile cut out, and can be installed on various uPVC or doors made of timber. Lever moveable pads are offered in a variety of finishes and can be used with a variety of multipoint locks. They are designed to be used with split spindle multipoint locks which have a 92mm cylinder centre and require a special split spindle set, as supplied by the lock maker.

They are compatible with various other Hoppe products, including patio door handles, french door handles, and window handles and come complete with an escutcheon for security.

It is comprised of two inline handles that can be locked and moved by a thumbturn cylinder, or keys. Pad handles are an alternative to a lever or lever handle.
